Markets Are Falling. But Is the Bigger Picture Really Changing?
Hoxton Blog • Markets Are Falling. But Is the Bigger Picture Really Changing?
A sharp sell-off in US technology stocks has unsettled investors, raising questions about artificial intelligence, company valuations, and the wider economy. But does this signal a deeper problem, or another period of market volatility?
After initially rallying following the US midterm elections, American stock markets reversed course on Thursday. The S&P 500 fell 4.4%, while the technology-heavy Nasdaq Composite lost 5.5%. Semiconductor companies, which manufacture the chips powering artificial intelligence (AI), were hit hardest, with the Philadelphia Semiconductor Index dropping 12.3%.
These are significant declines, but it is important to distinguish between a market correction and a fundamental deterioration in the economic outlook. Much of the weakness appears to reflect concerns about technology valuations, AI investment costs, and future company profits.
The AI Boom Faces a Reality Check
Artificial intelligence has driven considerable investor enthusiasm, with technology companies committing enormous sums to data centres, advanced chips and the electricity infrastructure needed to support them.
While the potential remains substantial, investors are increasingly questioning how quickly these investments can generate meaningful returns.
AI developers, including OpenAI and Anthropic, face greater scrutiny over whether revenues can grow sufficiently to justify their spending commitments. Meanwhile, the US midterm election results have raised the prospect of increased political scrutiny of data centre developments, particularly where electricity supplies are under pressure.
Higher borrowing costs add to these challenges. Although the yield on ten-year US government bonds eased to 4.8% on Thursday, it remains around 0.7 percentage points above its level at the start of the year. For businesses financing major infrastructure projects, this makes investment more expensive.
None of this suggests AI development is ending. Instead, investors are becoming more selective about which companies can turn technological progress into sustainable profits. Greater scrutiny of spending could ultimately benefit the sector.
Why Have Markets Fallen So Quickly?
One notable aspect of Thursday's sell-off was the absence of a single major event explaining its scale. This suggests investor behaviour, rather than a sudden deterioration in economic fundamentals, may have played an important role.
When markets perform strongly, investors can become heavily exposed to the same companies and sectors. If confidence weakens, some begin reducing their holdings, pushing prices lower and encouraging others to sell.
Hedge funds have reportedly been reducing their exposure to shares over recent weeks, with traditional investment managers also appearing to cut holdings. This may help explain the widespread selling across US markets.
However, the weakness was not reflected equally elsewhere. The UK's FTSE 100 fell just 0.4%, while US government bonds rose in value, helping cushion losses for some diversified investors.
Are Technology Shares Becoming More Attractive?
Following a substantial decline, investors naturally question whether shares now offer better value.
The Nasdaq 100 is reported to be trading at approximately 18 times its expected earnings over the next 12 months, its lowest valuation since March 2020. Put simply, investors are paying less for companies' anticipated profits.
However, lower valuations do not automatically mean shares are cheap. Much depends on whether businesses deliver the earnings growth currently forecast. If expectations weaken, share prices could face further pressure.
Technical indicators also suggest technology shares have become oversold in the short term, meaning prices may have fallen unusually quickly. Although this can sometimes precede a recovery, further weakness remains possible.
The key question is whether markets are simply reassessing expectations or whether the outlook for corporate profitability is deteriorating.
Could a Slower AI Boom Benefit the Economy?
The rapid expansion of AI infrastructure has created significant demand for electricity, specialist equipment, construction capacity and skilled workers. While supporting economic activity, this has also increased competition for resources and contributed to rising costs.
If companies become more selective about investment, some pressures could ease. Reduced competition for resources may help moderate inflation and potentially provide relief for borrowing costs.
A slowdown would also affect businesses benefiting from AI infrastructure spending, so the wider economic impact remains uncertain.
Nevertheless, a more measured approach could create a healthier environment, with investment directed towards projects offering clearer commercial benefits. Rather than signalling the end of the AI investment cycle, recent weakness may represent a shift towards more disciplined growth.
What Does This Mean for Investors?
The Nasdaq has entered correction territory, having fallen at least 10% from a recent high. Although unsettling, corrections are a familiar feature of stock market investing and do not necessarily signal a prolonged downturn.
Market declines can reflect economic weakness, changing expectations or investors reassessing valuations. Each correction is different, making it difficult to predict when markets will stabilise.
For investors, the priority should be avoiding short-term decisions that conflict with long-term financial objectives.
Diversification helps reduce dependence on individual sectors or regions, while understanding your investment time horizon provides perspective during downturns. Equally, your portfolio should reflect your circumstances and willingness to accept risk.
These principles cannot eliminate losses, but they can support more measured decisions when markets become unpredictable.
Keeping Perspective When Markets Are Unsettled
There will always be reasons for financial markets to experience weakness. Today, attention is focused on artificial intelligence, borrowing costs and technology valuations, but the factors influencing sentiment will change over time.
The recent sell-off raises legitimate questions about AI spending, corporate profitability and future growth. These developments deserve attention, particularly if concerns begin affecting the wider economy.
However, volatility remains a normal part of investing. Historically, long-term investors have experienced numerous periods of significant market weakness, although previous recoveries offer no guarantee of future outcomes.
Attempting to avoid every downturn is rarely practical, especially when markets can recover before the economic outlook becomes clearer.
The objective is not to predict every market movement, but to maintain an investment strategy capable of navigating uncertainty while remaining aligned with your long-term financial goals.
